Kare Kano: His and Her Circumstances(1995)

Yukino Miyazawa has it all - perfect grades, looks, the admiration of her peers. She's the #1 student at her school... at least she was until he showed up. The new boy, Soichiro Arima, one-ups her in every department. And the worst thing about it is that he's sincere! With her ego in jeopardy, Yukino will do whatever it takes to regain the spotlight, but falling in love was never part of it.
